Democratic prospects for regaining House control in the 2026 midterms remain the dominant driver behind the 87% outcome pairing a shutdown with Democratic victory, reflecting consistent generic ballot leads, special election swings, and nonpartisan ratings that show Democrats positioned to overcome the current narrow Republican majority. Persistent partisan divides over appropriations bills, particularly those tied to Homeland Security and immigration enforcement, have already produced multiple funding lapses in 2026 and continue to raise the probability of further lapses ahead of the November elections and subsequent sessions. Traders’ consensus incorporates these structural midterm headwinds for the president’s party alongside recurring procedural disputes that historically complicate passage of continuing resolutions or full-year spending measures by statutory deadlines.

The rules and resolution criteria are as follows:
1. Will there be another US government shutdown by January 31?
This market will resolve according to whether the U.S. Office of Personnel Management (OPM) announces another federal government shutdown due to a lapse in appropriations by January 31, 2026, 11:59 PM ET.
Partial shutdowns count as shutdowns; announcements of office closures due to holidays or inclement weather do not qualify as a shutdown.
The resolution source for this market will be OPM’s Operating Status page (https://www.opm.gov/policy-data-oversight/snow-dismissal-procedures/current-status/).
2. Which party will win the House in 2026?
This market will resolve according to the party that wins control of the United States House of Representatives in the 2026 United States midterm election.
A party wins control of the United States House of Representatives if it wins a majority of the chamber’s voting seats. If no party wins a majority of voting seats, the chamber will be deemed controlled by the party with which the first elected Speaker of the House of the Congress that convenes after the 2026 midterm election is affiliated.
The following rules govern the counting of seats for determining which party wins control of the chamber.
All House elections in the 2026 United States midterm election that elect voting members and determine representation in the upcoming 120th Congress are included. Where a seat is decided by a runoff, the runoff result will determine attribution of that seat.
Seats are attributed to the party under which the member was elected. If a member-elect changes party affiliation, or vacates their seat, between election day and the formal organization of Congress, the seat is attributed to the party under which the member was elected.
House members elected as independents who formally caucus with, or, for newly elected members, who announce their intent to caucus with a party are included in that party’s count. If the caucus decisions of members of the House elected as independents cannot be determined on the date of the election, this market may remain open until the earlier of (i) an announcement from the relevant members of their intents to caucus, or (ii) January 4th, 11:59 PM ET of the following calendar year. If no such announcement is made by January 4th, 11:59 PM ET of the following calendar year, the member will not count towards the seat count of any party.
The resolution sources for this market will be official information from relevant state electoral authorities, the United States Congress, and a consensus of credible reporting.
